Electrical fuses are metal fusible links which carry the current in the circuit being protected. Over-current protection may be provided by fuses as well as by circuit breakers, switches, relays and other devices. Fuses generally present the most cost-effective means for providing automatic high-voltage current protection against a single over-current failure. Most types of fuses are designed to minimize damage to conductors and insulation from excessive current. Fuses are widely used as overcurrent protection devices to prevent costly damage to electrical circuits. Fuse terminals typically form an electrical connection between an electrical power source and an electrical component or a combination of components arranged in an electrical circuit. The current path within a typical fuse is through the end caps or ferrules to a metallic fusible element. The resistance of the fusible element develops heat that causes a portion of the metal to melt or disintegrate upon reaching the melting temperature of the metal. These fuse links melt or vaporize at a given current level to open the circuit being protected. The basic fuse construction consists of a fusible element, a core to support this element, filler for enhancing the interruption of fault current at high voltages, and a housing to house the above components. The fuse housing materials may consist of glass, ceramic, porcelain, and glass-filament-wound epoxy tubing. Low energy fuses are employed in aerospace and other applications for transferring an explosive signal from one location to another and in providing precise delays or timing relationships between different energetic reactions which are initiated by the explosive signal. A time delay fuse is a type of fuse that has a built-in delay that allows temporary and harmless inrush currents to pass through the fuse without opening the fuse link or fuse links, yet is designed to open upon sustained overloads or short circuit conditions. Solid state fuses are known in which transistors and thyristors are placed in series with the load and turn off in response to a load fault condition.
